MACHINE FOR MAKING PEG-WIRE.

SPECIFICATION forming part of Letters Patent No. 319,771, dated June9,1885. Application filed January 24, 1885. (No model.)

To all whom, it may concern:

Be'it known that I, HENRY S. BACON, of Milford, in the county ofWorcester, State of Massachusetts, have invented certain new and usefulImprovements in Machinery for Mannfacturing Peg-Wire for Boot and ShoeNailing Machines, of which the followingisa full, clear, concise, andexact description, reference being had to the drawings accompanying andforming a part hereof, in which Figure 1 is a side elevation of mymachine. Fig. 2 is an end view of the grooving and finishing rolls andtheir operating mechanism, showing also the reels which hold themetallic strip and the waxed thread, all as shown in side elevation atthe upper right hand of Fig. 1..

Fig. 3 is a plan view of the mechanism for corrugating or grooving thewire, shown in side elevation at the lower part of Fig. 1. Fig. 4; is anend View of the same. Fig. 5 is an end view of the mechanism for layingthe finished peg-wire on the receiving-reel, shown at the upper lefthand of Fig. 1. Fig. 6 is a side elevation of the same. Fig. 7 is adetail of the corrugating device. Fig. 8 is asection on line w 00, Fig.2, of the gears which operate the grooving and finishing rolls. a

The object of my invention is the construction of a wire for use innailing boots and shoes which is composed of a central core of waxedthread or fine cord incased in a metallic covering,cylindrical incross-section,which is bent around and made to cover the threacompletely.

My invention consists in the mechanism, hereinafter more fullydescribed, which is adapted to take the thread and the metallic stripwhich form the wire from the supplyreels, groove or bend the flat stripinto atrough shape, lay the thread in the trough or groove, complete thebending of the wire over the thread so as to incase it, corrugate orroughen the surface of the wire thus formed, and lay the completed wireupon the receiving spool or reel, where it may be tied in bundles andtaken off as desired.

With the aid of the accompanying drawings the machine may be readilyunderstood.

Fig. 1 Shows the machine complete,with the parts for performing thevarious operations conveniently disposed with reference to each otherupon aframe or stand. It will be obvivious that this arrangement of theparts for bench A, I secure the frame B, provided with two uprightswhich support the arms a and b, which carry the supply-reels c and d,respectively. The reel 0 holds the metallic strip,

which passes from it between the groovingrolls f and f, provided,respectively,with concave and convex peripheries, which act upon theflat strip as it passes between them and groove or form it into a troughshape,whenee it passes through the guide 9, formed to receive it, andinto which the waxed thread also passes from the reel (1. (See Fig. 1.)As the thread passes into the guide y, it is laid intothe groove ortrough in the metallic strip,

and the strip and the thread in this relation pass between the concaveperipheries of the finishing-rolls h h, which finish the bending of thestrip and press it into a tube or cylinder around the thread. Thepeg-wire is then complete, but has not been corrugated. The wire A thenpasses, as shown in Fig. 1, over sheaves so arranged as to bring it intoposition to be passed through the corrugating-spindle j. V

This spindle'is arranged to revolve, and is provided on top with ahard-metal corrugating-tool, is, provided with a toothed cuttingedge,and so set (see, Figs. 3 and 7) with relation to the wire, which passesup through the hole It in the center of the spindle, as to bear upon thewire while the spindle revolves, and thus out a spiral groove or seriesof grooves in its surface, leaving it roughened or corrugated. Theset-screws k 70 Fig. 3, suitably secured to the top of the spindle,serve to lreep the finger k in a given position and permit of itsadjustment relatively to the wire.

After passing the corrugator the wire passes through a hole, l, in theguide-rod m, (see Fig. 5,) and is laid on the receiving-reel E. Thepurpose of. the guide-rod m is to lay the wire evenly on the reel, andto do this it is necessary that it should reciprocate horizontally,carrying the wire with it, and causing it to cross and recross the drumof the reel.

. easily slipped off, and has aremovableheami conveyed from this shaft,'thr6ugh"pu'lley'R,'tos" shaft F This shaft is providedwifh a grooved Toobtain this movement of the guide, I provide the following mechanism,(more fully shown in Figs. 5 and 6:) On the shaft F, which is mounted ina suitable supporting-frame, G, I secure a beveled gear, 3 arranged tomesh with another beveled gear, y, fast to'th'e upright shaft H, which.is mounted in supports from the frame. I, which meshes with the gear J,fast on shaft K, on which shaft is also secured the pulley L, providedwith a cam-path, n, cut in its periphery. A traveler, p, is secured. tontwoi rods, 1- and m, which slide in the frame-pieces G, and is providedwith a pin, 0, which bears in the cam-pathn, thus causing the traveler--p, the rod 1', and the guide-rod mlto reci-pro-i cate as the camrevolves. As the guide m reciprocates, it lays the strand of peg wireevenly in the coil on the'reel E. The reel-has acon: ical drum, so thatthe coil of wiremay bej' M, which maybe removed when it is neces- 7 6)in the heads of the reel enable "the operator to tie the coil of wirebefore removing it.

Thedriving-shaftP (see 1 and 2) ispro- Q vided with a driving-pulley, R,a'nd power is pulley R, whichis fastwith pulleyRflwhich in turn isbelted to'pulley It, whichgd'rives' shaft F. Shaft F 'is providedwithagear, H, which meshes with pinion H on small pulley, a', which isbelted to thegroovedi-p'uh ley a on the spindle y, andjthus motion iscommunicated to the" corrugating mechanism. (See Figs. 1 and 3.) I t Themain driving-shaft P'is provided with a small gear, b, which actuatesthe 'pairs'of gears b and b which drive, respectivelyfthe grooving andfinishing rolls. (See7Figs.;' 8 and. 2.) As thegrooving andfinishing;rollswear, they may require adjustment relatively to each.

other, and forother reasons it is desirable'to 1 i be able to adjustthem. In 'order that Imayj do this, I mount one of each of said rollsfOn this shaft is set the worm zontally by means of the dovetail shown ata,

and h in the blocks f and 'h, respectively These blocks are dovetailedto projecting parts of the supporting-frame, as shown at w, Fig. 2, andare provided with adj listing-screws w, tapped through and into theframe, and by means of which rolls f and h may be set toward or fromtheir companion rolls, f and h. (See Fig. 1.)

' Thesupply-reel 0 may alsobe adjusted hori- Fig. 1, in itssupporting-frame. This adjustment of the reel is necessary as the reelis used up, the reel beingshifted by the operator so as to bring thenext coil in line, it being necessary for the even paying off of themetal strip that the coil be substantially in line with the rolls,

astwill be obvious.

What I claim is 1. The combination, with the grooving-rolls f. f, of thearm (rand its adjustable reel-frame,

whereby-the" reel may be adjusted relatively tofthe rolls,;for thepurposes and substantially as; described.

2.Tlie fixed groovingand'finishing rolls f and h, in'combiiiatiohwith'the movable rolls f" and 71;, mounted iii the blocks f, and h, eacharranged to slide independently on their supports, and the hollowguideg, having an opening initswall for the passage of the thread orcord substautiallyas: described.

'3. 'Thejcombination, withithe fixed roll f, of the'irollf and .its'"block f dovetailed to thesupporting-frame, whereby the rolls may beadjusted relatively to each other, for the purposes and substantially.as specified.
